TTSX out of 300 wm?

[Panhandler80]

Any reason I shouldn’t be considering this bullet for ak moose? 180 grain overkill? Seems like a little more speed with 168 might be the way to go.

Can your 300wm stabilize a 180 grain ttsx? That's a long bullet. Other than that, it's more than enough. Our moose don't wear armor. The 168 would work just fine to.

My Tikka 300wm loves the 180gn TTSX. I have never shot a moose with it, but it has worked great on bear and deer so far.

I don’t know. Leaning towards the 168 anyway. With that monolithic bullet a lot of folks opt for lighter higher velocity bullets to aid in expansion and flatten trajectory.

26 inch barrel with 1:10 twist. Bergara. It has shot 3-4 other 180 grains just fine. Really likes Hornady SST.

I get that moose die easy with good shot. Solid copper just kind of intriguing in event that it’s Day 10 and a less than 100% perfect shot presents itself. Not going to take anything unethical, but some extra penetration and bone crunching might be nice to have.

I guide free range nilgai hunts in south Texas where we shoot well over 100 animals per year. My favorite caliber/bullet combo for nilgai is a .300 win mag shooting 180gr tsx or ttsx. Nilgai hate them!

not long ago I looked into the 165s and 168s TTSX and why they had 2 this is what Barnes said

Is the 168-grain .30-caliber TSX the same as the 165-grain TSX? Is it really a match-grade hunting bullet?

These bullets have different ogive geometries. The 165-grain TSX incorporates a shorter tangent ogive in the nose profile. It’s designed for cartridges with short magazines such as the .300 WSM and .300 Win Mag. The 168-grain TSX BT has a secant ogive which lengthens the nose profile and has shown superb accuracy downrange. It offers the best of both worlds because it’s also a premium hunting bullet offering exceptional terminal performance. It is best suited for cartridges such as the .308 Winchester, .30-06 and .300 Weatherby

I don't think it makes a huge difference especially if you have the bullets already but thought it was interesting.

Yep. Saw that on their FAQ page.

By all indications the 1:10 is plenty of twist for the 180 grain. Just read an article that says in 300wm the concern with twist taste really lies more on the lighter bullets. If they come out too fast they can over spin and loose accuracy. The rounds I’m looking at (in 168) from Choice Ammunition are coming out a good bit slower than that upper limit speed the article referenced for 150s. Talking bullets in general.

180gr copper mono is a good bit longer than 180gr lead. Length is the defining issue, not weight. Looks fine in a 10 twist 300wm. I'd probably not use in in an 11 unless you were always at altitude or never reaching out.. at all.

I'm a fan of the copper mono's as about everyone has reported, they punch above their weight due to the near 100% weight retention. A 162gr 30cal mono is my go to for Moose and bear.

I'm heading to AK for moose on Aug 29th. I've gotten a load worked up in my Tikka t3 lite with the 180 grain ttsx. It's rolling sub moa. 80 grains of Magnum powder (max is 82 grains according to book). With a federal large magnum primer in norma brass, I'm getting 3025 fps muzzle velocity. I chronod with the magnetospeed v3. I was honestly expecting more around 2900 fps so was happily surprised by 3025. I think that's a great amount of speed as many many many rifle calibers don't pump out the ttsx's that fast.

A moose will not be able to tell the difference between 12 grains...both bullets will work exceptionally well. The biggest thing with monos is that speed drives bullet expansion.

That is not applicable to mono metals, only thinly jacketed lead bullets (like some match bullets). There are guys shooting 124 grain monos 4000 fps out of their 300 RUM's with incredible accuracy, with 1-8" twist rates.

speed drives expansion, nearly 100% weight retention and if any m concern it is that of penciling a hole. That being the case, why NOT go for the slightly lighter. Especially if I’m likely 300 yards or less?

For my 300 WM, my order would be the 175 LRX, then 168 TTSX , then 190 LRX, followed by the 180 TTSX.

I like the better BC and lower expansion velocities of the first 3. That said my dad uses the 180 out of 30-06 on elk. They work and probably no discernable difference between the 4 at 300 yards.

 

[Panhandler80]

Can’t find any LRX.

Think I’m about to order a few boxes of 168 TTSX from Choice Ammunition.

I shoot 180gn ttsx out of my model 70 300wm and it's perfect moose medicine. I use my 7mm these days but the last moose I took with the 300 was @215 yards, hit a rib, went through the heart and lungs and stopped against the skin on the backside where it was recovered while cleaning.

okay… maybe I’ll go 180.

Looks like the 180 has better BC than 168. I get it, splitting hairs, but…

At $80+ per box and a sporty wait time I’m just torn, that’s all.

Oooof, are they going for $80 a box now? I still have a few boxes that are tagged $55 from like two years ago...my how inflation flies, when I bought that 300 I could get a box of decent ammo for $25. My wife has killed all her moose with 90gn .243 so don't get too hung up on numbers on paper and pick whatever your rifle likes best.

 

[Jim1187]

I'd be fine with any .30 cal TTSX or LRX from 130-190 grains you really are over thinking things if shots are going to be under 300yards.

Yes. I got the gun 2.5 years ago and Walmart had boxes for $20. So far gun has shot under 1” at 100 with every “cheap” round I’ve put through it. I’m sure the grounds I have now would work, but i don’t have very many and must buy more anyway.

 

[Panhandler80]

Okay. 168s on order. Let’s hope gun likes them… got 5 boxes. I suspect it will considering it’s history with every other off shelf ammo so far. They all been 180 copper / lead bullets, though. If it doesn’t I may have some discount 300wm 168br TTSX from Choice Ammo available in the not so distant future. $27’ shipping seems a bit silly as well.
